We are developing a conversational agent called VIBRANT to provide adaptive support for brainstorming in pairs in a scientific inquiry context. Our previous experimental study indicated that although adaptive support was effective for learning, it did not mitigate the negative influence of social interaction on idea generation. In this paper, we present a process analysis that makes the effect of the adaptive support on the idea generation process more apparent and suggests directions for future work. Keywords. Collaborative Learning, Process Analysis, Inquiry Learning
